Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531724, here are decompositions:

53 + 33531671 = 33531724
71 + 33531653 = 33531724
113 + 33531611 = 33531724
137 + 33531587 = 33531724
197 + 33531527 = 33531724
251 + 33531473 = 33531724
257 + 33531467 = 33531724
293 + 33531431 = 33531724

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.167.76.

Address: 1.255.167.76
Class: public
IPv4-mapped IPv6: ::ffff:1.255.167.76

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
